Ingeber was developed following a four-year €3m investigation programme by engineers in the company's Traction Division, which identified the energy conversion method. Ingeteam will install five of the systems in Brussels, which will contribute to Stib's efforts to reduce its energy bill and cut CO2 emissions by 40% by 2030.

Ingeteam has already installed Ingeber in Bilbao, Bielefeld and for Spanish track authority Adif in Malaga.
